Diễn đàn hỗ trợ Firefox

my Facebook page has shrunk, it is not fullscreen and you cant read it. it's like the whole page fits half of my screen and is so tiny how to I change it back to full view?

So about 5 days ago this problem started.

I've tried everything, uninstalling, reinstalling, installing older versions of Firefox, everything in the help file about this, going into about:config to set scanning to false, uninstalling my virus program (avast), etc.

They only thing I didn't try is restore points because they didn't go back far enough.

What could this possibly be? The moment the download finished it's absolutely gone.

I am a web developer. I tried HSTS (HTTP Strict Transport Security) in my developing website.

Now I want to cancel (forget) the HSTS setting for this site, but I cannot. Cannot I access my developing website with HTTP anymore?

How do I get ride of the dreadful CONDUIT SEARCH which has colonised my Firefox search like computer Herpes? I have tried a few of the replies but nothing has helped - it appears nowhere on any program list and even the following didn't do the trick :-

Owner AnonymousUser 1 year ago Several tried to but no one seemed to understand the real problem. I COULD, because it was mine too. So it follows the only ultimate solution:

1. Open Firefox 2. On the address bar, type – about:config in the URL. Press Enter.
3. You will be warned about Warranty. Click on “I’ll be careful…” 

4. On the Filter dialog box type – search.conduit 5. It will display all related entries. Right-click on Preferences Name and Reset. It worked for me, after trying a dozen of "fake" solutions. ;)

Other than serious chainsaw work, any ideas?

I was doing nothing in particular when I realized everything was text only with no graphics. When I opened the same page in Safari - happened to be gmail - the page appeared as it should with graphics. Text only is appearing on all sites opened in FF

Not only does firefox not show images, but also won't play audio online. Also my hotmail seems messed up, with text over text etc. It doesn't even show images on the firefox pages

How do I turn off this blocking message? "firefox prevented this page from automatically redirecting to another page " It used to be annoying, but now it has completely blocked me from logging in to a website.

i know to solve this problem by going about:config and to correct it,but i want to know whether is there any other way to block this dialog box. How all the user of my application will follow that ?

I am trying to print to a Zebra GK420d Label printer and firefox will not remember my paper size after one label is printed. Ideas on how to force a paper size and have it remember it?

I am on windows 7 and have changed my paper size for Printer Preference and Printer Properties and it will print correctly in notepad.

I had a virus on my computer so I had to reimage it, wiping out everything and starting new. I lost all my bookmarks (thankfully, I wrote them down before reimaging). Is there a way to email myself a file which contains my bookmarks, which I can then use to reload my bookmarks?

This sites (http://video.pbs.org/) drop downs "Programs" and "Topics" don't work when clicked. This page (http://www.modcloth.com/shop/dresses/ain-t-over-until-it-s-clover-dress) when clicking on the thumbnails of the green dress, the larger view pic does NOT change.

When appending param elements via createFragment the setAttribute javascript function does not set the "value" attribute. It is necessary to set the nodetext to add the this value attribute to the param element.

Second when using the latter method the generated html sets the "value" to the innerHTML. The resulting HTML when view by "Inspect" looks like this.

<param id="myID">myValue</param>

Note: [the element close text </param> is correctly displayed using Inspect but when using File->SavePageAs the ending text is not saved correctly. I have reported this in another Moz. question in FF Help.]

function setparamAttrs(parmID, parmVal) {

var gData = document.createDocumentFragment();

 var newNode = document.createElement("param");
 var textStr = document.createTextNode(parmVal);
 newNode.appendChild(textStr);

 newNode.setAttribute("id", parmID);
 //newNode.setAttribute("value", parmVal);  // this does not work
 //newNode.setAttribute("innerHTML", parmVal);  //this does not work

 gData.appendChild(newNode);
 document.body.appendChild(gData);

}

I was, however, able to retrieve the "value" after it was appended using:

var val = document.getElementById("parm0").value);

getAttribute("value") does not work either.

Finally I added the param elements to my HTML as this; <param id="myID">myValue</param>. I then attempted to extract the value using document.getElementById("myID").innerHTML. No text was returned. When I examined the HTML document with Inspect my HTML param element was displayed as <param id="myID">myVal. The closing element text was missing the same as when I use SavePageAs that I previously reported.

I am setting up a new laptop after a HDD crash. I have copied across my Data, from a back up Ext HD. I have my old IE "favourites", saved in folders as "internet shortcuts", on my new C drive.

Please, how do I get those favourites / bookmarks into FireFox?

I have read elsewhere that I have to import them first into IE, but the method described seems to only allow import of one file at a time. I have c 600 bookmarks.

I am using Win7 Home Premium and Firefox 10.0.01. I have IE9 on this computer.

Thanks
